Application filed July 10, 1912. Serial No. 708,646.

To all whom it may concern Be it known that I, JOHN V. DAVIS, a citizen of the United States, residing at Derby, in the county of Perry and State of Indiana, have invented new and useful Improvements in Land-Rollers, of which the following is a specification.

This invention relates to land rollers, the object of the invention being to provide a simple and reliable land rolling machine, embodying a particularly effective form and construction of land roller, and in connection therewith a revolving harrow, 1 attached so as to be especially adapted to easy manipulation or handling, for the purpose of breaking up the surface of the soil, and thereby facilitating the leveling of the ground in connection with the roller thereof.

A further object of the invention is toprovide means, under the ready control of the operator sitting on the machine, for elevating and depressing the revolving harrow, so that the latter may be used or not, as may be found desirable.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts, as will be hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the claims hereunto appended.

In the drawings: Figure 1 is a plan view of the machine. Fig. 2 is a side elevation thereof. Fig. 3 is a vertical central longitudinal section through the machine. Fig. 4 is a section taken lengthwise of the harrow shaft. Fig. 5 is an enlarged detail perspective view of the central portion of the harrow shaft, showing the means for adjusting the angle of the harrow teeth.

The frame of the machine is substantially rectangular, as illustrated in the plan view, Fig. 1, said frame comprising the front and rear bars. The frame also comprises a central fore and aft connecting member 5 which really constitutes the rear portion of the draft tongue or pole 6, the same being secured to the front and rear bars 1 and 2 by means of the clips 7 and 8.

Arranged at opposite sides of the tongue or central member 5 are weight boxes 9 and 10, the same extending lengthwise in parallel relation to the tongue, and being secured upon. the top of the main frame.

Mounted upon the weight boxes 9 and 10 is the drivers seat 11, preferably supported by means of springs 12 secured in any convenient manner to the weight boxes.

Beneath the frame is the roller shaft 13 mounted in bearings 14 in pendant brackets 15, in connection with which angle braces 16 extend from said brackets forward and upward, where they are secured by bolts or their equivalent to the under side of the main frame, as shown in side elevation. One or more additional brackets 15 extend downward from the central member or tongue 5, so as to support the shaft 13 about midway of its length.

J ournaled on the shaft or axle 13, at opposite sides of the central bracket 15 and the end brackets 15, are roller sections 17 and 18 provided on their outer peripheries with projecting lugs or teeth 19 which serve to break up the top surface of the soil, over which the roller is passing, thereby adding materially to the eflicient rollingdown and pulverizing of the surface of the ground.

Extending backward from the projecting extremities of the shaft 13 and journaled thereon are two draw bars 20, while arranged centrally between the rollers 17 and 18 is a central bifurcated draw bar 21. The draw bars carry at their rear ends a harrow shaft 22, consisting of a tube, around the center of which is a sleeve 23. The shaft 22 is provided with longitudinal series of holes 25, through which are inserted the harrow teeth. Any desired number of these harrow teeth may be employed in accordance with the size of the machine. The outer extremities of the shaft are reduced, as shown at 27, to adapt the same to be journaled in the rear ends of the draw bars 20. The sleeve 23 is provided at diametrically opposite points and at both ends with notches 28 receiving the adjacent harrow teeth 26, thus forming an interlocking connection or engagement between the sleeve 23 and the tubular harrow shaft.

In order to provide for elevating and depressing the harrow, I employ levers 29, fulcrumed at 30 on the machine frame, and connected by pendant links 31 to the draw bars 20. The levers 29 are operated by means of a hand lever 32 connected to a rock shaft 33 journaled in the bearings 34 on the machine frame, said rock shaft being provided with rearwardly extending arms 35 which are connected by means of links 36 to the forwardly extending arms of the levers 29. In connection with the lever 32,

I employ a segment rack 37 for holding said lever at any desired pointof adjustment In this way, the harrow shaft may be raised and lowered to any desired extent, whereupon the teeth will operate upon the ground, and serve to break up or disintegrate the same. 7

In order to set the harrow teeth at a forward or backward inclination, or at any intermediate point, I provide another hand lever 38 having connected to the lower end thereof plates 39 which are circular in form beneath the end of the lever proper to form oppositely arranged eyes 40 which encircle the sleeve 23 and fits up against the out side of each draw bar 21. This puts the two plates far enough apart to admit the lever 38, and also forms a square socket for the latch 41. The lever 38 is equipped with a thumb latch 41 which engages a notched circumferential flange 42 on the sleeve 23. It will now be seen that by rocking the lever 38, the shaft of the harrow may be turned to set the harrow teeth at any desired inclination, after which they may be locked by allowing thumb latch tl to move into 'en gagement with a notch in the flange 42.

43 represents a square sleeve embracing the plates 39 and the lever 38 and latch 41, and secured by bolts 44: to the lever 38. A coiled spring 45 holds the lever 38 in an upright position.

l/Vhat is claimed is:

1. A land roller, comprisingamain frame, a roller operating beneath said frame, a series of parallel draw bars journaled 0n the axle of the roller and extending rearwardly therefrom, a harrow shaft journaled in said draw bars, a notched circumferential flange fast on said shaft, and a thumb latch lever cooperating wit-h said flange for turning and locking the harrow shaft.

2. A land roller, comprising a frame, a sectional roller working under said frame, draw bars journaled on the ends of the roller axle, parallel central draw bars also journaled on the roller axle between the roller sections, a central sleeve journaled in said central draw bars and havingnotches' in the ends thereof, harrow shaft sections having their outer ends journaled in the end draw bars and their inner ends fitted in said sleeve, harrow teeth passing through the harrow shaft and engaging the notches in the sleeve, a notched circumferential flange on said sleeve, and a thumb latch lever engaging said flange. 7

In testimony whereof I affix my signature in presence of two witnesses.
